The rationale for this approach __48__ as follows. In wild-type C. elegans, che-22 __49__ expressed exclusively in pharyngeal muscle, whereas it __50__ expression of the pharyngeal muscle-specific myosin heavy chain gene myo-2. However, ectopic expression of che-22 in body wall muscle __51__ expression of myo-2. Because myo-2 __52__ normally never expressed in body wall muscle, this extopic expression assay provides a sensitive test for che-22 function. We __53__ two transgenic lines expressing an nkx2.5 cDNA under the control of the unc-54 body wall muscle-specific promoter. In both lines, we __54__ myo-2 expression in the body wall muscles (Fig. 1 A and B). These results __55__ that nkx2.5 can function like che-22 to induce myo-2 expression.41.A. can function B. could function C. can have functioned D. could have functioned42.A. express B. expressed C. have expressed D. had expressed43.A. was B. is C. has been D. had been44.A. is B. was C. had been D. has been45.A. activates B. activated C. has activated D. had activated46.A. could activate B. can activate C. could have activated D. can have activated47.A. was B. has been C. had been D. is48.A. generate B. have generated C. had generated D. generated49.A. detected B. detect C. have detected D. had detected50.A. showed B. show C. had shown D. have shownPart IIIDirections: Choose the one that best fits into the Discussion Section from the four choices marked A, B, C or D.DISCUSSIONThe p8 gene is barely expressed in NP but is overexpressed in acute pancreatitis (4, 12) . It is also strongly __56__ in pancreatic development and regeneration (4) . We have demonstrated that p8 is overexpressed in PC in the__57__ study. The characteristic expression of p8 is mainly attributable to its mitogenic activity (5) .__58__, p8 expression in PC would not be cancer-specific. __59__, it should be clarified whether p8 overexpression in PC is simply attributable to the excessive growth activity of cancer cells or to some genetic change(s), such as mutations.We __60__ the correlation between p8 overexpression and various clinicopathological parameters in PC. Larger tumors (>2 cm) showed a significantly higher overexpression rate of p8, and less differentiated types, advanced stages, and cases characterized by shorter survival tended to show p8 overexpression. These results also reflect the mitogenic activity of p8.__61__ reports (4, 5) have shown that p8 expression is induced by various proapoptotic __62__. It is suggested that p8 has an anti-apoptotic function (4, 5) . The significance of apoptosis in cancer cells is controversial. High spontaneous apoptosis is __63__ to be correlated with poor prognosis in PC (13) . If p8 has anti-apoptotic activity, p8 overexpression in PC cells would lead to resistance against apoptosis. Although we have not demonstrated the relationship between p8 and apoptosis in PC, the tendency toward shorter survival in p8-overexpressing cases is not __64__ with the past report (13) . It should be investigated whether p8 promotes PC cell growth through its anti-apoptotic activity.It is __65__ that p8 is a DNA-binding protein. As a transcriptional factor, it has a role in some phosphorylation/dephosphorylation signal pathways that involve its translocation to the nucleus and specific binding to DNA (4) . Potentially, p8 is phosphorylated by various kinases (4, 5) . Recent reports (14) showed that some kinases, such as the phosphatidylinositol 3-kinase or extracellular signal-regulated kinase, lead to inappropriate pancreatic cellular proliferation. Genetic mutations of K-ras, p16, and p53 in PC lead to cellular proliferation __66__ the phosphatidylinositol 3-kinase and/or the extracellular signal-regulated kinase pathways (14) . It is to be examined whether there is p8mutation in PC and how p8 participates in kinase signaling pathways.Recently, candidate of metastasis-1, a __67__ factor in human breast cancer, was identified (15) . Interestingly, p8 is structurally similar to candidate of metastasis-1 (15) . p8 might be __68__ in cancer metastasis, however, we could not find a significant difference in p8 expression between primary and metastatic lesions in our study. The relationship between p8 expression and cancer metastasis needs to be studied further.In __69__, we have demonstrated the overexpression of p8 in human pancreatic cancer. Our results suggest that p8 participates in the __70__ of pancreatic cancer, which reflects its mitogenic activity.51.A. induced B. reduced C. introduced D. seduced52.A. current B. / C. present D. former53.A. Thereafter B. Subsequently C. Additionally D. Therefore54.A. But B. Similarly C. However D. Consequently55.A. researched B. investigated C. discussed D. detected56.A. Previous B. Other C.

Read the passage and choose the best answer for each blank.Salt, shells or metals are still used as money in out-of-the-way parts of the world today.Salt may seem rather a strange 31 to use as money, 32 in countries where the food of the people is mainly vegetable, it is often an 33 necessity. Cakes of salt, stamped to show their 34 , were used as money in some countries until recent 35 , and cakes of salt 36 buy goods in Borneo and parts of Africa.Sea shells 37 as money at some time 38 another over the greater part of the Old World. These were 39 mainly from the beaches of the Maldives Islands in the Indian Ocean, and were traded to India and China. In Africa, shells were traded right across the 40 from East to West.Metal, valued by weight, 41 coins in many parts of the world. Iron, in lumps, bars or rings, is still used in many countries 42 paper money. It can either be exchanged 43 goods, or made into tools, weapons, or ornaments. The early money of China, apart from shells, was of bronze, 44 in flat, round pieces with a hole in the middle, called "cash". The 45 of these are between three thousand and four thousand years old-older than the earliest coins of the eastern Mediterranean.Nowadays, coins and notes have 46 nearly all the more picturesque 47 of money, and 48 in one or two of the more remote countries people still keep it for future use on ceremonial 49 such as weddings and funerals, examples of 50 money will soon be found only in museums.31.

Read the passages carefully and choose the best answer to each question.Passage OneWe can begin our discussion of "population as global issue" with what most persons mean when they discuss "the population problem": too many people on earth and a too rapid increase in the numberadded each year. The facts are not in dispute. It was quite right to employ the analogy that likened demographic growth to "a long, thin powder fuse that burns steadily and haltingly until it finally reaches the charge and explodes."To understand the current situation, which is characterized by rapid increases in population, it is necessary to understand the history of population trends. Rapid growth is a comparatively recent phenomenon. Looking back at the 8,000 years of demographic history, we find that populations have been virtually stable or growing very slightly for most of human history. For most of our ancestors, life was hard, often nasty, and very short. There was high fertility in most places, but this was usually balanced by high mortality. For most of human history, it was seldom the case that one in ten persons would live past forty, while infancy and childhood were especially risky periods. Often, societies were in clear danger of extinction because death rates could exceed their birthrates. Thus, the population problem throughout most of history was how to prevent extinction of the human race.This pattern is important to notice. Not only does it put the current problems of demographic growth into a historical perspective, but it suggests that the cause of rapid increase in population in recent years is not a sudden enthusiasm for more children, but an improvement in the conditions that traditionally have caused high mortality.Demographic history can be divided into two major periods: a time of long, slow growth which extended from about 8,000 B.C. till approximately AD. 1650. In the first period of some 9600 years, the population increased from some 8 million to 500 million in 1650. Between 1650 and the present, the population has increased from 500 million to more than 4 billion. And it is estimated that by the year 2050 there will be 6.2 billion people throughout the world. One way to appreciate this dramatic difference in such abstract numbers is to reduce the time frame to something that is more manageable. Between 8000BC and 1650, an average of only 50,000 persons was being added annually to the world's population each year. At present, this number is added every six hours. The increase is about 80,000,000 persons annually.1.Which of the following demographic growth pattern is most suitable for the long thin powder fuseanalogy?A. A virtually stable or slightly decreasing period and then a sudden explosion of population.B. A slow growth for a long time and then a period of rapid, dramatic increase.C. Too many people on earth and a few rapid increase in the number added each year.D. A long period when death rates exceeds birthrates and then a short period with higher fertility andlower mortality.2.During the first period of demographic history, societies were often in danger of extinctionbecause___.A. only one in ten persons could live past 40.B. there was higher mortality than fertility in most places.C. it was too dangerous to have babies due to the poor conditions.D. our ancestors had little enthusiasm for more children.3.Which statement is true about population increase?A. There might be an increase of 2.2 billion persons from now to the year 2050.B. About 50,000 babies are born every six hours at present.C. Between 8000 BC and the present, the population increase is about 80,000,000 persons each year.D. The population increased faster between 8000BC and 1650 than between 1650 and the present.4.The author of the passage intends to___.A. warn people against the population explosion in the near future.B. compare the demographic growth pattern in the past with that after 1650.C. find out the cause for rapid increase in population in recent years.D. present us a clear and complete picture of the demographic growth.5.The word "demographic" in the first paragraph means___.A. statistics of human.B. surroundings study.C. accumulation of human.D. development of human.PASSAGE BChinese Americans today have higher incomes than Americans in general and higher occupational status. The Chinese have risen to this position despite some of the harshest discrimination and violence faced by any immigrants to the United States in the history of this country. Long confined to a narrow range of occupations they succeeded in those occupations and then spread out into other areas in later years, when opportunities finally opened up for them. Today much of the Chinese prosperity is due to the simple fact that they work more and have more (usually better) education than others. Almost one out of five Chinese families has three or more income earners compared to one out of thirteen for Puerto Ricans, one out of ten among American Indians, and one out of eight among Whites. When the Chinese advantages in working and educational are held constant, they have no advantage over other Americans. That is in a Chinese Family with a given number of people working and with a given amount of education by the head of the family, the income is not only about average for such families, and offer a little less than average.While Chinese Americans as a group are prosperous and well-educated Chinatowns are pockets of poverty, and illiteracy is much higher among the Chinese than among Americans in general. Those paradoxes are due to sharp internal differences. Descendants of the Chinese Americans who emigrated long ago from Toishan Province have maintained Chinese values and have added acculturation to American society with remarkable success. More recent Hong Kong Chinese are from more diverse cultural origins, and acquired western values and styles in Hong Kong, without having acquired the skills to proper and support those aspirations in the American economy. Foreign-born Chinese men in the United States are one-fourth lower incomes than native-born Chinese even though the foreign-born have been in the United States an average of seventeen years. While the older Hong Kong Chinese work tenaciously to sustain and advance themselves, the Hong Kong Chinese youths often react with resentment and antisocial behavior, including terrorism and murder. The need to maintain tourism in Chinatown causes the Chinese leaders to mute or downplay these problems as much as possible.6.According to the passage, today, Chinese Americans owe their prosperity to___.A. their diligence and better education than others.B. their support of American government.C. their fight against discriminations.D. advantages in working only.7.The passage is mainly concerned with___.A. Chinese Americans today.B. social status of Chinese Americans today.C. incomes and occupational status of Chinese Americans today.D. problems of Chinese Americans today.8.Chinatowns are pockets of poverty, as is probably associated with___.A. most descendants of Chinese Americans are rebelling.B. most descendants of Chinese Americans are illiterate.C. sharp internal difference between Chinese coming from different cultural backgrounds.D. only a few Chinese Americans are rich.9.Which of the following statements is not true according to this article?A.As part of the minority, Chinese Americans are still experiencing discrimination in Americantoday.B. Nowadays, Chinese Americans are working in wider fields.C. Foreign-born Chinese earn lower income than native-born Chinese Americans with the similaradvantages in the U.S.D. None of the above.10.According to the author, which of the following can best describe the older Hong Kong Chinese andthe youngerA. Tenacious; rebellion.B. Conservative; open-minded.C. Out-of-date; fashionable.D. Obedient; disobedient.IV. Translation (20%)Directions: Translate the following passage into Chinese.More people than ever now work from home for part or all of the week. Such flexibility can seem a good idea, but many people find it difficult to manage their time. Working from home in isolation can also prevent people from engaging in the daily interpersonal relationships that working life can offer –and which can help creativity and improve our mental well-being.In an ordinary workplace, we are helped in our time management by the fact that our access to many temptations is limited. We don’t have to constantly monitor ourselves as our colleagues or bosses are likely to be doing so. While we might bemoan our lack of choice about what we do and when – such as attending a two-hour meeting – we can also be relieved of the need to make choices about what to do next.But when working from home, temptations abound which can eat up our time. Food is in the fridge or can be bought in a quick trip to the shops. Excitement of all kinds can be easily accessed through social media, websites or games which will enthrall us. For some, the temptations to use their time “badly”, particularly onlin e, can be very seductive. At any moment there is a delicate balance of power within: between our creative, constructive side and the side which seeks easier gratification and mindlessness.V. Writing(20%)Directions: Write an essay of about 200 words according to the following prompt. A title is needed.The past few years have witnessed a mounting number of universities allowing students to evaluate their teachers and even decide if they can stay on their positions. Some say that students know the most clearly about the performance of a teacher; some say it is dangerous to leave the right to students to evaluate teachers. Is it up to students to evaluate their teachers? What’s your opinion?You are to write in three parts.In the first part, state specifically what your opinion is.In the second part, provide one or two reasons to support your opinion.In the last part, bring what you have written to a natural conclusion or make a summary.Marks will be awarded for content, language and organization.。

PART I: Cloze (20 points)Directions: Choose the best word(s) for each numbered blank.Every street had a story, every building a memory. Those 1 with wonderful childhoods can drive the streets of their hometowns and happily 2 the years. The rest are pulled home by duty and leave as soon as possible. After Ray Atlee had been in Clanton (his hometown) for fifteen minutes he was 3 to get out.The town had changed, but then it hadn’t. On the highways leading in, the cheap metal buildings and mobile homes were gathering 4 possible next to the roads for maximum visibility. This town had no zoning whatsoever. A landowner could build anything with no permit, no inspection, no notice to 5 landowners, nothing. Only hog farms and nuclear reactors required 6 and paperwork. The result was a slash-and-build clutter that got uglier by the year.But in the older sections, nearer the square, the town had not changed at all. The long shaded streets were as clean and neat as when Ray roamed them on his bike. Most of the houses were still owned by people he knew, or if those folks had passed on the new owners kept the lawns clipped and the shutters painted. Only 7 were being neglected. A handful had been 8 .This deep in Bible country, it was still an unwritten rule in the town that little was done on Sundays 9 go to church, sit on porches, visit neighbours, rest and relax the way God 10 .It was cloudy, quite cool for May, and as he toured his old turf, killing time until the appointed hour for the family meeting, he tried to 11 the good memories 12 Clanton. There was Dizzy Dean Park where he had played little League for the Pirates, and there was the public pool he’d swum in every summer except 1969 when the city closed it 13 admit black children. There were the churches—Baptist, Methodist, and Presbyterian—facing each other 14 the intersection of Second and Elm like wary sentries, their steeples 15 height. They were empty now, but in an hour or so the more faithful would gather for evening services.The square was as 16 as the streets leading to it. With eight thousand people, Clanton was just large enough to have attracted the discount stores that had 17 so many small towns. But here the peopl e had been faithful to their downtown merchants, and there wasn’t a single empty or boarded-up building around the square—no small miracle. The retail shops were mixed in with the banks and law offices and cafes, all closed for the Sabbath.He inched 18 the cemetery and surveyed the Atlee section in the old part, where the tombstones were grander. Some of his ancestors had built monuments for their dead. Ray had always 19 that the family money he’d never seen must have been buried in those graves. He parked and walked to his mother’s grave, something he hadn’t done in years. She was buried among the Atlees, at the far edge of the family plot because she had barely belonged.Soon, in less than an hour, he would be sitting in his father’s study, sipping bad instant tea and receiving instructions on exactly how his father would be laid to rest. Many orders were about to be given, many 20 and directions, because his father (who used to be a judge) was a great man and cared deeply about how he was to be remembered.Moving again, Ray passed the water tower he’d climbed twice, the second time with the police waiting below. He grimaced at his old high school, a place he’d never visited since he’d left it.

Passage 1LAPD Chief Charlie Beck's tenure has helped answer questions that lingered after the Rampart consent decree ended and outsider Chief William J. Bratton stepped down: Has L.A.'s policing culture permanently changed? Or with outsider chiefs and federal monitors gone, will the Los Angeles Police Department return to its brutal, secretive and racially-tinged past?A department veteran who, under Bratton's tutelage, became a true believer in data, transparency and change, Beck helped instill a more open, reform-oriented culture. He was successful in part because he's smart and his heart was in the right place, but also because he is old-school LAPD, son of a cop, sibling to and father of cops. His embrace of departmental reform in the post-Rampart era was a strong signal to the rank-and-file, to the city's political leaders and to communities that often suffered brutal policing tactics that the new thinking and new practices were there to stay.Beck announced Friday that he would step down in June, before the end of his second and final five-year term.Even though he is not elected, he is a savvy politician who correctly read what the mayor, the Police Commission and the people of Los Angeles wanted from him and what to an extent he was able to deliver: low crime, no scandals, little controversy. He became adept at the regular radio interview and the soundbite on immigration enforcement and criminal justice reform.At a time of national awakening and outrage over police shootings of unarmed AfricanAmerican men and boys, Beck and the LAPD often looked good in comparison, at least for a while.But there have been troubling exceptions. Just days after a police officer fatally shot Michael Brown in Ferguson, Montana., LAPD officers shot another unarmed African American man, Ezell Ford, in Los Angeles. Beck concluded that the shooting was justified despite his police commission's finding to the contrary. His action, and District Attorney Jackie Lacey's decision a year ago not to prosecute —along with numerous other officer-involved shootings —have exacerbated tension between the department and many of the communities it patrols.Beck's decision was to respond to an increase in violent crime in South Los Angeles with increased patrols and what amounts to an L.A.-style stop-and-frisk policy (automobile stops for arguably pretextual reasons such as broken taillights, in order to search for weapons).Did the tactic work? The violence eventually abated, but not before police reopened old wounds and reinvigorated anti-police sentiment in communities that felt over-patroled. Activists' calls for Beck's firing became a common feature at weekly commission meetings.Meanwhile, although Los Angeles continues to enjoy historically low crime rates, the declines began a slight but troubling reverse in 2015. The scandal-free ledger was tainted by the 2013 rampage of fired officer Christopher Dorner, who posted a manifesto of charges against the department, then killed four people and wounded three others before dying as police closed in on him. LAPD officers wounded three innocent bystanders in their sometimes frenetic quest to track down Dorner. There was a scandal of another sort when police cadets, aided by an officer, stole cruisers and other equipment. Their exploits went undetected for weeks.Beck earns high marks for managing an inherent tension faced in recent decades by every LAPD chief. In a city in which public safety accounts for more than 80% of the city budget, he faced strong pressure in City Hall and many communities to economize. At the same time, many of the same critics want him to provide better patrols in lower-crime parts of the city while still being able to respond in force to spates of violence in high-crime communities, and while employing a more community-oriented approach to policing citywide. Accomplishing all of those goals simultaneously is simply not possible.Beck is the fourth LAPD chief to be appointed under a key change that followed the 1992 riots, which were sparked by acquittals of officers in the brutal beating of African American motorist Rodney King. After decades in which chiefs could retain their jobs virtually for life, leaders of the department are now appointed to a single five-year term and can be appointed to a second — but no more. Chiefs Willie Williams and Bernard Parks were denied second terms. Bratton won a second but left early for other opportunities. Beck's June departure date leaves plenty of time for the commission and Mayor Eric Garcetti to consider a host of would-be replacements among the younger brass whom Beck has mentored.Comprehension Questions:21. To what extent has the Los Angeles Police Department changed under Beck?A. Permanently.B. Until he steps down.C. Not at all.D. Temporarily.22. Which of the following statements is NOT true?A. Charlie Beck’s protecting LAPD officers aggravated the re lationship between the departmentand the communities.B. Charlie Beck’s policy of increasing patrols and the stop-and-frisk policy have beencontroversial among the local people.C. Christopher Dorner was angry with the LAPD and abreacted his dissatisfaction by killinginnocent people.D. The LAPD will return to a brutal, secretive, and racially-tinged past after Chiefs WillieWilliams and Bernard Parks’ retirement.23. Why do you think activists' calls for Beck's firing became a common feature at weeklycommission meetings?A. He was maladroit in radio interview and the soundbite on immigration enforcement andcriminal justice reform.B. When Americans were outraged over police shootings of unarmed African Americans, LAPDunder Beck’s leadership did w ell.C. Beck earns high marks for managing an inherent tension faced in recent decades by everyLAPD chief.D. The increased patrol of the police aroused an anti-police sentiment in communities.24. Which of the following can be the last sentence of the passage?A. It's imperative that Beck's successor be someone who can build on his legacy and continuemoving the department down the path of reform.B. After announcing on Friday that he would step down in June before completing his secondterm on the job, Beck reflected on his LAPD career of more than 40 years.C. Charlie Beck, whose own career with the Los Angeles Police Department spanned four decades,will retire this summer, ending an eight-year tenure as police chief.D. Charlie Beck was credited with major reforms in the department and a general decline inhomicides but also had some missteps.25. What is the author’s attitude toward Charlie Beck as chief of Los Angeles Police Department?A. Cynical.B. Neutral.C. Prejudiced.D. Critical.Passage 2We are in a global health crisis, and it grows worse by the year, as the World Health Organization has warned that by 2030 almost half the world’s population will be overweight or obese if current trends continue. There are already 124 million obese children, a more than tenfold increase in four decades, and more than a million of these live in the UK, which has the worst obesity rates in western Europe. Four in five will grow up to be obese adults; and the leader of the UK’s paediatric body warns that this will cost them 10 to 20 years of healthy life.This is a social problem, both in cause and consequence, as concurred by Simon Stevens, the chief executive of the UK’s National Health Service, whose cautioning that obesity could bankrupt the health service comes across as the placard-wielding stance of a roadside prophet of doom - yet the government’s response has been as modest and inadequate as these figures are shocking. Medical experts describe its childhood obesity strategy as weak, embarrassing and even insulting. Though it inherited a tax on sugary drinks, it rowed back from restrictions on price-cutting promotions and junk food marketing or advertising, leaving its strategy to rely heavily on measuressuch as school activity programmes.Campaigners had warned that would not be enough; now research proves they were right –even when such initiatives tackle both diet and exercise, and make efforts to reach out to families. Children in schools in England’s West Midlands were given a year of extra ph ysical activity sessions, a healthy eating programme and cookery workshops with their parents, all of which failed to have any significant effect on children’s weight.The causes of the obesity epidemic are multiple and complex, as the landmark Foresight report produced over a decade ago underscored: we live in an obesogenic environment, and some more so than others (more than twice as many children in deprived areas are obese as in affluent areas). TVs and smartphones in bedrooms and reliance on cars play their part; so too do food deserts, where fruit and vegetables are expensive or inaccessible, which leaves the more economically strapped sector of the population choosing to fill a hungry child with donuts rather than apples.But one factor leaps out: greed. The problem is not gluttony by a generation of Augustus Gloops but the avarice of the Willy Wonkas who press junk food on consumers, then profess surprise at the results. The tactics of big food are, as the global health organisation Vital Strategies points out in its report Fool Me Twice, strikingly similar to those of big tobacco over the years. But big food has the advantage that everyone needs to eat, while no one needs to smoke, and that a biscuit does not damage health as a cigarette does, obesity notwithstanding. Thus, these companies tell us that we should not restrict individual freedom; that it is up to people to show self-discipline; and that their products are fine as occasional indulgences - never mind that they present family-size packs as if they are suitable for individuals, nor that highly processed foods, packed with salt and sugar, tend to be cheaper to produce, store and deliver – as well as being habit-forming.Other countries have been far bolder in tackling the industry, instead of relying on voluntary action. In Latin America, governments have forced companies to remove cartoon characters - naturally an instant appeal to young children - from cereal boxes, imposed junk food taxes and ordered school tuck shops to replace high-salt/sugar products with fruit and vegetables. Tougher rules reshape consumer perceptions and decisions and in doing so, they can also push companies into changing products.A ban on junk food advertising before the 9pm watershed is long overdue. It should be su pplemented by a ban on promotions and price cuts for “sharing” bags of chocolates, as Action on Sugar urged last month, and the sugar tax on drinks could be extended to food products, with the revenue channelled into initiatives making fresh produce more affordable and attractive to consumers. The government’s failure to force change means that the rest of us will pay the price –in ill health and higher taxes – as big food rakes in the profits.Comprehension Questions:26.

She had a lot to say about Europe. Some of it—“Do we dare more Europe? Yes, we do dare”—made the news. But outside the hall many Davos participants paid her no mind. They loitered in various lounges carrying on conversations with each other. They talked and talked—as though they hadn’t been talking all day. They had talked while sitting on panels or while skipping panels that others were sitting on. “Historic Complexity: How Did We Get Here?,” “The Compensatio n Question,” “Global Risks 2012: The Seeds of Dystopia”: over the course of five days, a man could skip more than two hundred and fifty such sessions.Davos is, fundamentally, an exercise in corporate speed-dating. “Everyone comes because everyone else co mes,” Larry Summers told me. A hedge-fund manager or a C.E.O. can pack into a few days the dozens of meetings—with other executives, with heads of state or their deputies, with non-governmental organizations whose phone calls might otherwise have been ignored—that it would normally take months to arrange and tens of thousands of Gulfstream miles to attend. They conduct these compressed and occasionally fruitful couplings, the so-called bilateral meetings, either in private rooms that the W.E.F. has set aside for this purpose or in hotel rooms, restaurants, and hallways. All that’s missing is the hourly rate.Many Davos participants rarely, if ever, attend even one. Instead, they float around in the slack spaces, sitting down to one arranged meeting after another, or else making themselves available for chance encounters, either with friends or with strangers whom they will ever after be able to refer to as friends. The Congress Center, the daytime hub, is a warren of interconnected lounges, cafés, lobbies, and lecture halls, with espresso bars, juice stations, and stacks of apples scattered about. The participants have their preferred hovering areas. Wandering the center in search of people totalk to was like fishing a stretch of river; one could observe, over time, which pools held which fish, and what times of day they liked to feed. Jamie Dimon, running shoes in hand, near the espresso stand by the Global Leadership Fellows Program, in the late afternoon. Fareed Zakaria, happily besieged, in the Industry Partners Lounge, just before lunch. The lunkers would very occasionally emerge from their deep holes (there were rumors of secret passageways) and glide through the crowd, with aides alongside, like pilot fish. (The W.E.F. says that Davos is an entourage-free zone, but this doesn’t seem to apply to the biggest of the big wheels, like heads of state.) It is said that the faster you walk the more important you are.It is a name-dropper’s paradise. Central bankers, industrial chiefs, hedge-fund titans, gloomy forecasters, astrophysicists, monks, rabbis, tech wizards, museum curators, university presidents, financial bloggers, virtuous heirs. I found myself in conversation with a newspaper columnist and an executive from McKinsey & Company, the management-consulting firm. This was serendipitous, as so many conversations in Davos turn out to be, because, at the urging of many, I was supposed to be angling for an invitation to the McKinsey party, at the Belvedere Hotel. A must, people said, with a glint. I was suspi cious, owing to an incongruity between the words “party” and “management consulting.” But this was Davos. The executive cheerfully added me to the list. A McKinsey for a Merkel: a fair trade.The newcomer hears repeated bits of Davos advice. Ride the shuttle: you might meet someone. Go to a session that deals with a subject you know nothing about: you might learn something. Come next year, and the one after, if they invite you back: you might begin to understand. Everyone says that you can’t get the hang of Davos until you’ve been three or four times. So many things are going on at once that it is impossible to do even a tenth of them. You could spend the week in your hotel room, puzzling over a plan, wrestling with your doubts and regrets, but a person who would do this is not the kind who would be invited to Davos.Another admonition: no matter how much you do, you will always have the sense that something else, something better, is going on elsewhere. On the outskirts of town, three men are hunched in the candlelit corner of a pine-panelled Gaststube, discussing matters of grave importance. You may think you don’t care about such things, but the inkling burrows like a tapeworm. The appetite for admittance can become insatiable. Whenever I passed through town, I noticed men in good suits and sturdy boots, walking with intent in the opposite direction. Where were they going? They ducked into tea shops or into Mercedes sedans with darkened passenger windows. “Wheels within wheels,” one woman whispered to me. “What happens in Davos stays in Davos,” many people said, but even when you’re there it’s hard to know what is happening in Davos. Yossi Vardi, an Israeli tech investor and an eighteen-year Davos veteran, said, “What you see here, in the Congress Center, is just twenty per cent of the action.”There are as many Davoses as there are perceptions of Davos. Schwab might use the term “stakeholders,” and the stakeholders may be partial to the word “silos,” but another term that springs to mind when you are there i s “cliques.” A certain ferment occurs where the cliques overlap, but as often as not they pass in the night.Comprehension Questions:31. The World Economic Forum (“WEF”) in Davos is a very important world event mainlybecause________________.A. The important lectures about world economic problems by world leadersB. People mingleC. Non-Governmental Organization can raise capital by meeting with governments andcompaniesD.

The greatest fear of WEF participants is_______________.A. Not making enough business contactsB. Not being able to attend future eventsC. Being left out of the loopD. Giving out business secrets35. When participants attend the WEF they immediately fall into “cliques”. By “cliques” the writermeans_______________.A. Participants meet other participants that can bring business and can share valuable informationB. Participants meet other participants with shared values and interestsC. Participants meet other participants for a common causeD. Participants can meet other participants with different interests and valuesPassage 4A new degree of intellectual power seems cheap at any price. The use of the world is that man may learn its laws. And the human race has wisely signified their sense of this, by calling wealth, means - 'Man' being the end. Language is always wise.Therefore I praise New England because it is the place in the world where is the freest expenditure for education. We have already taken, at the planting of the Colonies, the initial step, which for its importance might have been resisted as the most radical of revolutions, thus deciding at the start the destiny of this country - this, namely, that the poor man, whom the law does not allow to take an ear of corn when starving, nor a pair of shoes for his freezing feet, is allowed to put his hand into the pocket of the rich, and say, "You shall educate me, not as you will, but as I will: not alone in the elements, but, by further provision, in the languages, in sciences, in the useful and in elegant arts. The child shall be taken up by the State, and taught, at the public cost, the rudiments of knowledge, and, at last, the ripest results of art and science".Humanly speaking, the school, the college, society, make the difference between men. All the fairy tales of Aladdin or the invisible Gyges or the taIisman that opens kings' palaces or the enchanted halls underground or in the sea, are any fictions to indicate the one miracle of intellectual enlargement. When a man stupid becomes a man inspired, when one and the same man passes out of the torpid into the perceiving state, leaves the din of trifles, the stupor of the senses, to enter into the quasi-omniscience of high thought - up and down, around, all limits disappear. No horizon shuts down. He sees things in their causes, all facts in their connection.One of the problems of history is the beginning of civilization. The animals that accompany and serve man make no progress as races. Those called domestic are capable of learning of man a few tricks of utility or amusement, but they cannot communicate the skill to their race. Each individual must be taught anew. The trained dog cannot train another dog. And Man himself in many faces retains almost the unteachableness of the beast. For a thousand years the islands and forests of a great part of the world have been led with savages who made no steps of advance in art or skill beyond the necessity of being fed and warmed. Certain nations with a better brain and usually in more temperate climates have made such progress as to compare with these as these compare with the bear and the wolf.Victory over things is the office of man. Of course, until it is accomplished, it is the war and insult of things over him. His continual tendency, his great danger, is to overlook the fact that the world is only his teacher, and the nature of sun and moon, plant and animal only means of arousing his interior activity. Enamored of their beauty, comforted by their convenience, he seeks them as ends, and fast loses sight of the fact that they have worse than no values, that they become noxious, when he becomes their slave.This apparatus of wants and faculties, this craving body, whose organs ask all the elements and all the functions of Nature for their satisfaction, educate the wondrous creature which they satisfy with light, with heat, with water, with wood, with bread, with wool. The necessities imposed by his most irritable and all-related texture have taught Man hunting, pasturage, agriculture, commerce, weaving, joining, masonry, geometry, astronomy. Here is a world pierced and belted with natural laws, and fenced and planted with civil partitions and properties, which all put new restraints on the young inhabitant. He too must come into this magic circle of relations, and know health and sickness, the fear of injury, the desire of external good, the charm of riches, the charm of power. The household is a school of power. There, within the door, learn the tragicomedy of human life. Here is the sincere thing, the wondrous composition for which day and night go round. In that routine are the sacred relations, the passions that bind and sever. Here is poverty and all the wisdom its hated necessities can teach, here labor drudges, here affections glow, here the secrets of character are told, the guards of man, the guards of woman, the compensations which, like angels of justice, pay every debt: the opium of custom, whereof all drink and many go mad. Here is Economy, and Glee, and Hospitality, and Ceremony, and Frankness, and Calamity, and Death, and Hope.Comprehension Questions:36. What is the passage mainly about?A. The power of human civilization.B. The relationship between man and nature.C. Man learning the laws of society.。

管理可以分为很多种类,比如行政管理、社会管理、工商企业管理、人力资源管理、情报管理等等。在现代市场经济中工商企业的管理最为常见。每一种组织都需要对其事务、资产、人员、设备等所有资源进行管理。每一个人也同样需要管理,比如管理自己的起居饮食、时间、健康、情绪、学习、职业、财富、人际关系、社会活动、精神面貌(即穿着打扮)等。企业管理可以划为几个分支:人力资源管理、财务管理、生产管理、物控管理、营销管理、成本管理、研发管理等。在企业系统的管理上,又可分为企业战略、业务模式、业务流程、企业结构、企业制度、企业文化等系统的管理。
Passage 2(15points)
管理科学包括的内容,按照其抽象程度,可分为管理哲学、管理学原理和管理学三个层次。管理是一种工作,是人们为实现一定目的而进行的一种活动。管理是管理者为达到一定的目标,运用组织、计划、指挥、控制等职能,来协调组织内各项事务和各种资源的合理组合和利用的一种活动。由此可见,一切管理都是由三个基本要素组成:管理的主体,即管理者;管理的客体,即管理的对象,由人和事组成的一个动态系统;管理的效果,即管理主体作用于管理对象而产生的预期结果,即实现的管理目标。在管理系统中,管理者是管理的主体,在管理中占主导地位,起主导作用。
Passage 1(20points)
The natural philosophy of the Ionians was a series of bold speculations, shrewd guess, and brilliant intuitions rather than the outcome of extensive and careful scientific investigations. These men were perhaps a little over-eager to see the whole picture and so jumped to broad conclusions. But they did discard the older, largely mythical accounts and substituted materialistic and objective explanations of the design and operation of the universe. They offered a reasoned approach in place of fanciful and uncritical accounts and they defended their contentions by reason. These men dared to tackle the universe with their minds and refused to rely on gods, spirits, ghosts, devils, angels, and other mythical agents who might maintain or disrupt nature’s happenings. The spirit of these rational explanations can be expressed in the words of Anaxagoras: “Reason rules the world.”
Passage2(15points)
In the beginning there was an explosion. Not an explosion like those familiar on earth, starting from a definite center and spreading out to engulf more and more of the circumambient air, but an explosion which occurred simultaneously everywhere, filling all space from the beginning, with every particle of matter rushing apart from every other particle. “All space” in this context may mean either all of an infinite universe, or all of a finite universe which curves back on itself like the surface of a sphere. Neither possibility is easy to comprehend, but this will not get in our way; it matters hardly at all in the early universe whether space is finite or infinite.
Passage 1(20points)
管理是人类各种组织活动中最普通和最重要的一种活动。近百年来,人们把研究管理活动所形成的管理基本原理和方法,统称为管理学。作为一种知识体系,管理学是管理思想、管理原理、管理技能和方法的综合。随着管理实践的发展,管理学不断充实其内容,成为指导人们开展各种管理活动、有效达到管理目的的指南。

At about one-hundredth of a second, the earliest time about which we can speak with any confidence, the temperature of the universe was abut a hundred thousand million (1011) degrees Centigrade. This is much hotter than in the center of even the hottest star, so hot, in fact, that none of the components of ordinary mater, molecules,or atoms, or even the nuclei of atoms, could have held together. Instead, the matter rushing apart in this explosion consisted of various types of the so-called elementary particles, which are the subject of modern high-energy nuclear physics.
